Ways of determining reservoir pressure during PTA.
The purpose of this webinar is to give basic knowledge of determining reservoir pressure during well testing. To define the extrapolation methods, their features, to demonstrate strengths and weaknesses. Training is conducted in the form of audiovisual delivery (presentation) and subsequent discussion and answering trainees questions.
- quality improvement of well testing;
- improved monitoring of field development;
- cost saving on ineffective measurements and testing;
